Abstract

The invention relates to light-color heat-conducting thermoplastic resin and a preparation method thereof. The thermoplastic resin comprises PC resin, high-temperature-resistant resin, a heat-conducting filler, a lubricating agent, a toughening agent and an antioxidant. By optimizing the high-temperature-resistant resin and the lubricant, the product is especially suitable for occasions with higher requirements on use environments, especially for the fields of household appliances, industrial machines and the like which have the heat resistance requirements of 150 DEG C or above, need good heat dissipation performance, need to be matched into light colors or color colors and have requirements on toughness.

Description

technical field [0001] The invention belongs to the field of engineering plastics, in particular to a light-colored heat-conducting thermoplastic resin and a preparation method thereof. Background technique [0002] Polycarbonate resin is a general-purpose engineering plastic, which has the advantages of transparency, impact resistance, heat resistance, dimensional stability, etc. The heat-resistant temperature of PC is between 120-130 ° C. For some high-heat-resistant fields , such as above 140 ℃, PC will have deformation problems. In addition, the thermal conductivity of thermoplastic resins is poor, and the thermal conductivity is mostly between 0.1-0.3W / (m K), and the scattering performance is poor. When used as some internal heating appliances, the heat cannot be dissipated in time, resulting in a reduction The service life of the appliance. [0003] In order to improve the thermal conductivity of the resin, a large amount of thermally conductive fillers are added to ...
